IRIS Technical Deep Dive: File Formats, Data, Schemas, and Validations

Is your team ready for the IRS FIRE-to-IRIS transition? Join us for the second webinar in Sovos’ Goodbye FIRE, Hello IRIS webinar series!

As organizations prepare for the IRS transition from the FIRE platform to IRIS, the technical impact on 1099 reporting processes becomes impossible to ignore. The shift from the longstanding 1220 flat file to IRIS’s complex XML structure represents more than a new formatting requirement – it fundamentally changes how data must be prepared, validated, transmitted, and corrected.
